A0.5 kg block of aluminum (caluminum=900j/kg⋅∘c) is heated to 200∘c. the block is then quickly placed in an insulated tub of cold water at 0∘c (cwater=4186j/kg⋅∘c) and sealed. at equilibrium, the temperature of the water and block are measured to be 20∘c. if the original experiment is repeated with a 1.0 kg aluminum block, what is the final temperature of the water and block? if the original experiment is repeated with a 1.0 kg copper (ccopper=387 j/kg⋅∘c) block, what is the final temperature of the water and block? if the original experiment is repeated but 100 g of the 0∘c water is replaced with 100 g of 0∘c ice, what is the final temperature of the water and block? if the original experiment is repeated but 100 g of the 0∘c water is replaced with only 25 g of 0∘c ice, what is the final temperature of the water and block?
